STRAIGHT-HANDIED VIBRATORY RAZOR.

Application led November 21, 1924. Serial No. 751,225.

This invention relates to safety razors of the class in which arelatively thin blade is confined upon a base constructed With guardfingers, and usually referred to as the comb, by means of a removablecap; the blade being held against displacement in the plane of the razorby means of pins fixed upon one of the confining members and passingthrough openings in the blade.

ln my application, Ser. No. 678,136, filed December 3, 1923, I havedisclosed a razor with a blade and mounting arranged in this manner, butin which the handle extends from the mountinglr in a directionsubstantially perpendicular to the plane of the blade, the blade being'arranged to vibrate upon the mounting by having the openings Whichreceive the fixed pins elongated in the direction of vibration, and thehandlebeing equipped with electrically energized vibratory mechanism,one element of which extends from the handle in a position to impartvibration to the blade.

The primary object of the present invention is to adapt a suitablevibratoi'y mechanism, for instance, that described in my application`above identified, to a razor having its blade mounted in substantiallythe manner aforesaid, but' in which the handle is in the nature of ashank or shaft extending ina direction substantially parallel to theplane of the blade after the manner of a so-called straight razor; andaccordingly one feature of the present invention consists in mountingCil als

a vibrator at or near one end of a laterally ofisetting shank or handleand the vibratory razor blade at the other end thereof, While theintermediate portion of the shank serves for prehension in themanipulation of thel razor; and connecting the transmitting member ofthe vibrator with the blade through means of a longitudinallyreciprocating thrust member mounted in the handle or shank and providedat its respectivel ends with means for establishing driving connectionwith the blade and the transmitting member.

A further object to provide a design of connecting rod which Will bevery cheap to produce in accurate form, very light in structure, readilyresponsive to vibratory force and very conveniently assembled anddisassembled with the shank or handle and with the elements with whichit cooperates at its respective ends. Accordingly another fea-. ture ofthe invention consists m constructing the shank or handle in tubularform, preferably of two members united through longitudinal tongue andgroove'joints so that one slides into position upon the other, andconfining the connecting rod in the housing thus provided and betweenthe said members thereof in a manner to guide it in its right-linemovement Without imposing undue frictional or other resistance to itsaction; the en'd of the connecting rod which receives the vibratingelement being fashioned 'in the form of a yoke which embraces saidelement when the vibratory mechanism is placedV in position upon thehandle, and the end of the connecting rod Which'drives the blade beingin t-he formof a slide fitted in a bed formed in the guard and carryinga stud which projects through acentral opening in the blade.

A still further object is to coordinate the the shank and the other bythe vibrator, rotatable one Within the other, and of Which the innercylindrical member is circumferentially slotted to admit the actuatingend of the vibrator to the yoke of the connecting rod, and

permit said inner cylindrical memberto ro tate in the aforesaid rightand left hand adjustment of the razor; to which end, the yoke islikewise laterally open to the admission of the operating end of thevibrator through an angle of at least 180. Preferably,l kthe innercylindrical member is held Within the outer member by means of a plugunited to the end of the inner cylindrical member in a manner to impartturning movement thereto, and said plug is fashioned in a manner toconstitute it a convenient means for impartingy the rotation incident tothe right and lefthand adjustment referred to.

Another object is to provide an improved driving connection for avibratory razor blade of the type in which the blade, instead Fig. 1;

of being mounted on a carriage Whiclris guided for reciprocation, slidesdirectly upon aiixed base upon which it is guided by pins extendingthrough velongated holes in the blade While receiving its drive from astud intersecting its center, which driving connection Will besubstantially free from tendency to displace the blade from its axis ofreciprocation, and therefore impose less Wear upon the guiding pins andless load upon the motor. Accordingly, another feature consists inproviding at the center of the blade, and intermediate of its elongatedguiding openings -which occur near its ends, a hole for the drivingstud, which is of relatively large diameter as compared with thetransverse diameter of the guiding openings and the Width of the blade,the diameter of this driving hole being preferably somewhat more thanone-third of the Width of the blade, With the result that a superiordriving effect is insured, there is substantial reduction in thetendency to cause sidel impingement of the blade upon the aligning pins,and the arrangement admits ofthe use of a more stable driving stud.

Further objects relate to details of construction Which are particularlyappropriate to the economical realization of the several objects alreadystated, and will be fully understood from the ensuing detaildescription.

In the accompanying drawing Fig. 1 is a side elevation of a straighthandled razor With the confining cap removed and a portion of the handlein section, in an intermediate longitudinal plane of Figure'2;

Fig. 2 is a section on line 2"- of Fig. 1;

Fig. 3 is a transverse section on the line 3"-8 of'Fig. 1; Y

Fig. 4 is a section on the line 4".-4" of Fig. 5 is a section on theline 5*-5* of Fig. 1;

Fig. 6 is a section .on the line 6"-6 of Fi l; and A lig.v 7 is asection on the line 7"- x of Fig. 1.

Figure Sis a detail View of the spring clip that secures the cap to theblade mounting.

1 represents the baseof the blade mounting, which is constructed with'guard fingers 2, and which will be hereinafter referred to as the comb.3 represents the blade resting upon the comb 1 'and confinedagainstvdisplacement in the plane of theblade by means of the pins 4,fixed in the comb; and 5- represents the cover which contines the bladeupon the comb and which is removably secure-d in place by means o f aclip- 6 having key hole slots 6a (Fig. 8), which engage the necks 7 ofthe pins 4 and hold the cap at a fixed distance from the comb, therebyconiining the blade without resisting its free-- dom of vibration.Preferably the cap 5 rests firmly upon the heads of the pins 4, whichthus become the means for spacing the cap from the comb, and the clips 6have suiicient resiliency to draw the cap snugly against the pins. 8represents the handle which is in the form of a shank extending from thecomb 1 substantially in the plane of the blade and thus adapting therazor to be manipulated after vthe manner of a so-called straight razor.The handle 8 is constructed of the shank 9 which extendsnfromethecomband which is made trough-shaped for the dual purpose of lending rigidityto the structure and providing a portion of the housing for theconnecting rod 10 that is to transmit Vibration to the blade; also acover member 11 which interlocks with the shank 9, by a slidingmovement, and through the `medium of tongue and groove joints 12. Shank9 terminates at its outer end in a cylindrical ferrule 13 embraced by asleeve 14, Which equips the handle for receiving a vibrator, forinstance, the vibrator 15, constructed substantially in accordance withmy application hereinbefore identified; and the ferrule 13 is securedagainst axial displacement in the cylindrical sleeve 14 through means ofa shouldered plug 16 entering the outer end of thel sleeve 14 and at thesame time abutting against the same, and a screw 17; the end of theferrule 13 being constructed `with a pair of segmental Walls 18, bestshown by dotted lines in Fig. 6, which are lapped by the head of thescrew, and the plug 16 being provided with a noncircular neck 16a thatenters the opening left between said Walls 18 to adapt the plug,

' through its perforated end 16", to rotate the ferrule 13 and throughit the shank 8\ and head 1 of the razor.

Sleeve 14 provides for convenient assembly of the vibrator 15 throughmeans of a threaded bushing 19 fixed in the boss 2O of the sleeve andwith which the vibrator 15 engages through the medium of its threadedend 21. A

The connecting rod 10 confined in the tubular handle, as explained, isconstructed on its outer end with a yoke 22 presented in position toreceive the vibratory element 23 of theA vibrator 15; said yoke 22, asbetter shown in Fig. 5, being designed to substantially iit and beguided in the ferrule 13, and being laterally open for at least 180around its longitudinal axis to permit turning relatively to thevibratory element 23 in revolving the razor, and the said ferrule havingan arcuate slot. 24 to admit the said vibratory element 23 Within it,and extending circumferentially a distance which permits at least onehundred and eighty degrees of angular adjustment of the vibratorrelatively to the plane of the razor blade. The inner end of connectingrod 10 is designed with a slide 25 iitted in a guide bed 26 whichconstitutes the bottom of the guard 1; and this slide 25 has a stud 25afixedly mounted in it in position to extend through the blade 3 and thusserve as means for connecting the blade with the slide and causing theblade to partake of the slides vibration.

In assembling the several parts as above described, the sleeve 14 beinglongitudinally fixed by means of plug 16 and screw 17 relatively to theferrule 13 on the shank 9, and the vibrator 15 being removed,theconnecting rod 10 with its slide 25y is first placed in position withits slot b engaged over a pin 4, which brings the slide in its bearingsin the bed 26, and presents its yoke 22 in position to receive thevibratory element 23. Cover member 11 is then slid longitudinally alongthe shank 9, until its end 11a (Fig. 2) brings up against the ferrule13. The blade 3 is then place-d in position with the posts 4 and thestud 25a projecting through it, and cap 5 is put on and slidlongitudinally to- Ward the cover member 11 until it abuts against it.Vibrator 15 may be screwed into position at any time after the yoke ofthe y connecting rod 10 has reached position to receive vibrator member23.

When thus assembled, the razor is supported by the vibratory housing 15and turned, it' necessary, to reverse the presentation of the facialside of the comb 1 to suit the convenience of the user, and it is thenmanipulated in the act of shaving through the medium of the handle 8,such reversal to position being repeated as often as is necessary. y j

The device constructed and assembled, as herein described, is peculiarlyadapted for production largely by shaping sheet metal of suciently thingage to insure lightness of the parts and thus the construction andassembly are made very cheap and efficient in use.
